For example, most low-end processors provide only one external-interrupt input pin and only one address vector in memory for the service routine that processes external IRQs (interrupt requests).

This paper describes the method of using one accelerometer interrupt pin for both wakeup and non-motion detection to automatically switch on and off the screen. The microprocessor only needs to ...

As Arm-based infrastructure continues to scale across markets, demands on system components increase. This can mean more interrupts, or signals from hardware/software to a processor to pause a task ...

CPU architecture, memory interfaces and management, coprocessor interfaces, bus concepts, bus arbitration techniques, serial I/O devices, DMA, interrupt control devices. Including Design, construction ...

Using the sysinternal process explorer, i have discovered that what is labelled as Interrupts and DPCs are eating up more than 30% of my CPU time.

The big issue is the interrupts and shared memory used by devices to communicate with the CPU. The shared memory that the devices use for communication is all based on physical memory addresses.

Progress to-date includes successful porting of Linux 5.10, including Tachyum Interrupt Controller (TIC), inter-processor interrupts (IPI), and running with Symmetric Multiprocessing System (SMP ...

DLX is an open source microprocessor, it’s free and it has never been implemented in a commercial ASIC (Application Specific Integrated Circuit) design. The objective of this project is to use the ...
